In Ubuntu, we added support to grub for installing to multiple ESP,
using a wrapper around grub-install that does the same debconf stuff
as we do for grub-pc; called grub-multi-install.

We have not yet had time to forward this, and I'm not sure if the
solution is acceptable for Debian, but it's certainly my hope that
we can reduce this and the rest of the delta we have downstream.
